foojay — a place for friends of OpenJDK

For my book “Getting Started with Java on Raspberry Pi”, an example was described to store sensors and measurements in an H2-database through REST APIs with a Spring application on the Raspberry Pi.

The application takes some time to start on a Raspberry Pi, and Adam Bien who does the airhacks.fm podcast, asked me if I could compare this to a similar Quarkus application, which resulted in some nice results.
